Rexroth A4VG71 ye-Compact Drive Systems
Uhlolojikelele nezincazelo ezibalulekile
I A4VG71 iyinhlobo ipampu ye-axial-piston enomthamo oguquguqukayo, yohlobo lwe-swashplate ku-yokushayela kwe-hydrostatic okuvaliweyo. Inezici zokuhamba kwejometri ezingu-71 cm³/rev, i pressure eyinhloko engu-400 bar, futhi ingcindezi ephezulu engu-450 bar. Ngaphakathi kwesivinini esiphezulu salolu hlobo (n max ≈ 3300 rpm ku-Vg max), ukuhamba okucabanga cishe 234 L/min. Izicelo ezijwayelekile zifaka izinhlelo zokushayela ezihlanganisiwe ekwakhiweni nasezimotweni zezimboni lapho kudingeka amandla aphezulu nokulawula okuphendulayo.

Izici eziyisisekelo nokuvikela
Ukugeleza kungu-kuhlobene nesivinini sokushayela nokuhamba, futhi zingaba ihlukahlukene ngaphandle kokuphazamiseka ukusuka ku-zero kuya phezulu ngokulungisa i-swashplate angle; ipompo ukuphendula ukuhamba kahle ngokusebenzisa i-neutral.
Amabili ama-valve wokukhulula aphezulu ohlangothini lwe-high-pressure bavikela ukudluliswa komjikelezo ovaliwe (iphampu nomshini) ekukhathaleni; lezi futhi zisebenza njenge-ama-valve wokukhuphula (boost).
I-i-charge pump ehlanganisiwe ihlinzeka ngama-pilot kanye ne-oli yokulawula; i umfutho omkhulu wokushaja ikhawulelwe yi-relief yangaphakathi.
Ukuphuma kwengcindezi iyis standard yokunciphisa ingcindezi ephezulu yesistimu futhi yehlise ukusebenza kokukhulula okungadingekile.
Umdwebo ophathekayo, oqinile one-through‑drive amandla okungeza ipampu eyengeziwe yosayizi ofanayo egumbini elifanayo.
Izinketho zokulawula nokusetshenziswa okuvamile
Imindeni yokulawula ifaka: NV (akukho ukulawula), DG (i-hydraulic eqondile), EZ (amandla kagesi amaphuzu amabili), HD (i-hydraulic, ephathelene nengcindezi), HW (i-servo yomshini), EP (electro‑proportional), DA (i-hydraulic, ehlobene nesivinini). Khetha uhlobo oluhambisana nesu lakho lokulawula uhlelo, impendulo, kanye nesixhumi esibonakalayo.
Izicelo ezijwayelekile ze-A4VG imindeni (kuhlanganisa usayizi 71) ziyizinto ukushayela okuvaliweyo ku imishini yokwakha kanye izinhlelo zezimboni njengokuthi amatshe okuhlobisa, ama-roller anokudlidliza, abavuni, izithwala zekhola, abathuthi beemitha, kanye nezinye izinhlelo zokushayela ezincane ezidinga amandla aphezulu nokusebenza okuqinisekisiwe kokuphuma okuvaliweyo.
Imodeli yekhodi kanye nezikhombisi zokuhweba
Umndeni we-A4VG usebenzisa ikhodi yohlobo olwakhiwe (isibonelo, usayizi, idivayisi yokulawula, isiphakamiso sochungechunge, ukufakwa/ukudlula, kanye nohlobo lokuklama). Izibonelo zezinhlobo ezisebenzayo ze-A4VG71 zihlanganisa:A4VG71DA1DT4/32R‑NZF02F001DH, A4VG71EP2D1/32R‑NZF02F011SH‑E, A4VG71HWD1/32R‑NZF02F001S. Ngaso sonke isikhathi hlanganisa i-ikhodi yohlobo ephelele ohlwini lwezingxenye zomshini wakho kanye ne-iphampu ye-nameplate ukuqinisekisa ukuhambisana kokulawula nokwakhiwa okufanele.
Izidingo zokwethulwa nokugcinwa
Pre‑fill kanye ukuphuma umjikelezo ovaliwe; qinisekisa ukuthi i-ipampu yokushaja iyalungiswa futhi uwoyela uhlangabezana nezidingo ze-OEM zokuhlanzeka kanye ne-viscosity.
Qinisekisa ukudlula ukuhlela nokuhlanganisa ukuphumula; hlola case drainukuhamba nokushisa ngesikhathi sokuqala.
Seta ama-valve okukhulula ingcindezi ephezulu kanye nanoma yini efakwe ukucisha ingcindezingokwespecs zemishini; hlonipha ibanga lokulungisa lokulawula nokuphendula.
Hlola futhi, uma kudingeka, shintsha i-i-charge strainer/filter; qinisekisa zonke izixhumanisi zikagesi ze-variant yokulawula ekhethiwe.
Ngemuva kokuqala, hlola futhi ukukhala, ukuvibrisha, nok leaking, futhi uqinisekise ukuthi ukuphendula kokulawula kuhambisana nokuziphatha okulindelekile ngaphansi kwengcindezi ephansi nephezulu.
